Cooling Mode
When the ECO switch is turned ON during cooling, the A/ C ECU limits the power consumption of the
electric inverter compressor in accordance with the room temperature.
The A / C ECU does not limit the power consumption very much (C
2
shown in the graph below), and
prioritizes decreasing the room temperature when the room temperature is high (T
2
or above). When the
room temperature decreases to T
1
or below, the A/ C ECU limits the power consumption of the electric
inverter compressor C
1
and restrains the cooling performance. This prevents the SOC (state of charge)
of the HV battery from decreasing and increases the amount of engine OFF time, improving the fuel
economy.
NOTE:
ECO mode control is performed only when the blower motor is ON. When the ECO switch is
turned ON while the blower motor is OFF, the ECO switch indicator light and the heater control
panel LCD display illuminate, but ECO mode control is not performed.
During cooling under ECO mode control, the room temperature is maintained at 25
C (77
F)
even if the set temperature is below 25
C (77
F). Since the power consumption of the electric
inverter compressor is limited under ECO mode control, this does not indicate a malfunction.
To decrease the room temperature to below 25
C (77
F), the MAX COLD temperature [18
C
(64.4
F)] must be selected or ECO mode control must be canceled by turning the ECO switch
OFF.
